'Purity' in the Bible

But I fear, lest by any means, as the serpent beguiled Eve in his craftiness, your minds should be corrupted from the simplicity and the purity that is toward Christ.

Let no man despise thy youth; but be thou an ensample to them that believe, in word, in manner of life, in love, in faith, in purity.

the elder women as mothers; the younger as sisters, in all purity.
